Patent GB-837950-A (GB)
Title: New polyglycol ether derivatives and process for their manufacture
IPC: C08G59/50
Filed: 1956-07-13
Abstract: The invention comprises polyglycol ether amides of the formula <FORM:0837950/IV (b)/1> and acid addition salts (e.g. acetates) and quaternary salts of such compounds, in which R1 and R2 represent saturated or unsaturated aliphatic hydrocarbon radicals such that the residues R1 and -OC-R2 each contain at least 8 carbon atoms and together contain at least 20 carbon atoms, A represents a group -(CH2-CH2-O)k-CH2-CH2-OH, B a group -(CH2-CH2-O)r-CH2-CH2-OH and C a group  -(CH2-CH2-O)s-CH2-CH2-OH (where k, r and s are each whole numbers, the sum of k, r and s ranging from 19 to 99 when m is 2 and the sum of k and r ranging from 19 to 99, when m is 1), and m and n represent 1 or 2.  The compounds are prepared by reacting 20 to 100 mols. of ethylene oxide with a compound having the formula <FORM:0837950/IV (b)/2> Specification 718,010 also is referred to.ALSO:Polyglycol ether derivatives having the formula <FORM:0837950/IV(c)/1> and acid addition salts and quaternary salts of such compounds, in which R1 and R2 represent saturated or unsaturated aliphatic hydrocarbon radicals such that the residues R1 and -OC-R2 each contain at least 8 carbon atoms and together contain at least 20 carbon atoms, A represents a group -(CH2-CH2-O)k-CH2-CH2-OH, B a group -(CH2-CH2-O)r-CH2-CH2-OH and C a group -(CH2-CH2-O)s-CH2-CH2-OH (where k, r and s are each whole numbers, the sum of k, r and s ranging from 19 to 99, when m is 2 and the sum of k and r ranging from 19 to 99 when m is 1), and m and n represent 1 or 2, are used for softening viscose artificial silk and as levelling and stripping agents in the dyeing of nitrogenous fibres.  The compounds are particularly applicable to the dyeing of chlorinated and unchlorinated wools from aqueous acid or neutral baths with complex chromium or cobalt compounds of monoazo-dyestuffs in which one atom of metal is bound in complex union with two molecules of azo-dyestuff and which metal compounds are free from carboxylic acid and sulphonic acid groups or contain not more than one such group.  Specification 718,010 also is referred to.ALSO:Polyglycol ether amides of the formula <FORM:0837950/IV (a)/1> and acid addition salts and quaternary salts of such compounds, in which R1 and R2 represent saturated or unsaturated aliphatic hydrocarbon radicals such that the residues R1 and -OC-R2 each contain at least 8 carbon atoms and together contain at least 20 carbon atoms, A represents a group -(CH2-CH2-O)k-CH2-CH2-OH B a group -(CH2-CH2-O)r-CH2-CH2-OH and C a group -(CH2-CH2-O)8-CH2-CH2-OH (where k, r and s are each whole numbers, the sum of k, r and s ranging from 19 to 99 when m is 2 and the sum of k and r ranging from 19 to 99 when m is 1), and m and n represent 1 or 2, are prepared by reacting 20 to 100 mols. of ethylene oxide with a compound having the formula <FORM:0837950/IV (a)/2> quaternary and acid addition salts being obtained by subsequent treatment with a quaternating agent or an acid (e.g. acetic acid).  The compounds are used as softening agents and as levelling and stripping agents in dyeing processes. Specification 718,010 also is referred to.
